To achieve greater fertilizer coverage, you need to increase the flow rate. Covering the field more slowly will allow more fertilizer to be applied in a given area, thereby increasing the coverage. Among the following options:
A. Increasing speed to approximately 7.1 mph would result in covering the field more quickly, which would decrease the fertilizer coverage.
B. Increasing the engine speed to approximately 2,000 rpm might increase the flow rate, but it may not address the specific need to slow down the coverage.
C. Decreasing speed to approximately 6.0 mph would lead to covering the field more slowly. This slower speed would allow more fertilizer to be dispensed over the same area, thereby achieving greater coverage.
D. Shifting to second gear so that the engine speed slows would likely decrease the overall efficiency and effectiveness of the fertilizer distribution process.
Given the options, the most appropriate method to increase fertilizer coverage would be:
C. Decrease speed to approximately 6.0 mph so that you cover the field more slowly.
This approach directly addresses the need to apply more fertilizer per unit area by reducing the speed at which the field is covered.
